Quizplus · Accepted Answer

An operational definition is a statement that describes how a researcher manipulates an independent variable. This definition is important to ensure that other researchers can replicate the study and understand how the independent variable is being manipulated. A control condition is a comparison condition that is used as a baseline for comparison in an experiment. Replication refers to the process of repeating a study to see if the same results are obtained. A hypothesis is a tentative explanation for a phenomenon that is based on previous observations and research.
